Rehabilitation of artisanal gold mining land in West Lombok, Indonesia: Characterization of overburden and the surrounding soils

  This study was carried out to characterize the overburden materials and soil properties of artisanal mining at Sekotong, West Lombok, Indonesia to suggest an appropriate rehabilitation technology.  The results of the study showed that the properties of overburden materials from Sekotong artisanal mining has a relative neutral acidity (pH about 6.4), however, with time together with the formation of...

Application of characteristics method for flood routing (Case study: Karun River)

  Open channel flows often come in investigation and intervention scope of the environment engineering. Very often, the water layer depth is weak compared to the horizontal extension of the observed phenomena. This is the case for flows in rivers or channels and of the ground run off. The transition from turbulent Navier-Stokes equations tackled by using the Leibnitz formula. A series of approximation allowing...
